Which do you prefer: e-mail or email? If you prefer the former and write for the Associated Press, expect for your knuckles to get rapped by a pernicious editor, as the AP Stylebook has just declared that “e-mail” is no longer correct. From now on, we don’t send e-mails, at least according to the AP; we send emails.The announcement comes through the AP Stylebook’s official Twitter account, which notes:Language evolves. Today we change AP style from e-mail to email, no hyphen. Our editors will announce it at #ACES2011 today Email isn’t the only change rolling out through the Associated Press today. Another big tech change for the AP is abandoning the space in cellphones and smartphones (it used to be “smart phone” and “cell phone”). The acronym of CPR is no longer clarified, and Calcutta — which everyone has heard of — will now be Kolkata, which no one knows.The changes go into effect at 3AM ET tomorrow morning. It’s worth noting, of course, that this is hardly a universal decree: the AP Stylebook is simply a list of guidelines the AP uses to make its own copy consistent. Newspapers do tend to follow the AP, but that’s just because most newspapers depend so much on AP content, and if they don’t follow the Stylebook, their own content won’t be consistent. It’s a path of least resistance thing.I think Gizmodo’s got a good take on this:Why is this such welcome news? Because language is catching up to technology. Because those videos of animals riding slightly larger animals you forward around aren’t just “electronic mail” anymore, digital versions of what you stuff in a dark blue mailbox. They’re now a form of communication unto themselves. Next up? E-books. E-paper. Get ready. There’s becoming increasingly little point differentiating the electronic from the analog.via GizmodoUpdate – This change is not in the 2010 Stylebook but is available in the AP Stylebook available on BlackBerry (through the BlackBerry App World).
